JOINT-MACHINE AND WELT-CUTTER.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed December 14, 1907. Serial No. 406,424.

welt has been cut or the shoe jointed, much diificulty has beenexperienced in securing the required smoothness of the upper at theshank and the desired neatness of the joint. This is due to the factthat in the welting operation the running on and off of the stitchingwhich occurs at the point of joint between the heel seat and shank tendsto throw out the rib of the inner sole and leave the inner scam in aposition which so far overlies the margin of the inner sole that whenthe outer sole is stitched to the welt the table will strike the innerseam and thus guide the stitch away from its true line along the shank.When the shoe is trimmed therefore there is a liabilitythat the trimmerwill run into the stitching which will expose the same and ruin theshoe. In order to overcome this difficulty and secure the desired resultwithout the delay'caused by the slowness of hand work and clumsiness ofthe result, I have devised my present invention which automaticallyengages with the welt and upper at the required point and draws themsmoothly over the last, presses back the inner seam to its normalposition, and securely holds them while the operative fastens them inplace.

This invention I have more fully disclosed in the accompanyingspecification in which I have described a machine which embodies myinvention and in addition to this description I have set forth in thedrawings forming a part of the specification views of such an embodimentto illustrate the principle of my invention.

Throughout the specification and drawings like reference numeralsindicate corre-.

sponding parts and in the drawings Figure 1 is a side view-of mymachine, Fig. 2, an end view partly in section, Fig. 3, a plan view,Fig. 4, a perspective view showing a shoe positioned and underoperation, Fig. 5,

a section of the welted and lasted upper at the shank, and Figs. 6 and 7views of the cutting knife.

1 is a bed in which is formed a longitudinal slideway 2. 3 is a slidemovable along said slideway and bearing a support 4 which through thecoiled spring 5 affords a yielding support for a last 6 on a block 7which is hinged on said slide 3. 8 is an adjustable toe support alsomounted on the slide 3.

9 is a pair of oppositely disposed boxes in which are formed transverseslideways.

11 is a pair of oppositely disposed transverse slides which are normallyretracted by the springs 10 in the slideways 10 and are simultaneouslyoperated therein by means of bell-crank levers l2 pivoted in the boxesat 1-3 and having engagement at their upper ends with the slides 11 andat their lower ends connected by suitable rods to a treadle or otheroperating means (not shown). On the slides 11 are adjustably mountedpressure fingers 14 formed with crooked ends 14 which are adapted toslide over a last to draw the upper smoothly over it. The ends of thesebent portions 14: are brought to a thin slightly rounded edge 14: whichis adapted to catch the upper :20 and welt 21 at the seam 22, draw themsmoothly over the last and at the same time press back the rib 23 to itsnormal position.

15 is a stop on the upper face of each finger 14: near its edge 14 onthe side opposite to the shoe. As the welt end runs over this stop theoperative may out against it with a skiving cut allowing the welt to besevered uniformly on the two sides of the shoe.

16 is a stop adjustable at 16 to afiord the proper location of shoes ofdifferent sizes and thuspermit the operative to out quickly slightlyforward. When the heel strikes the stop 16 the slides 10 are thrownforward by the levers 12 which are operated by any suitable means suchas by foot treadle or by a power shaft. As the slides 10 advances thefingers 14 engage the seam 22 of the upper 20 and the welt 21 at theshank and cooperating with the upward pressure of the springs 5 and"?draw the upper smoothly over the last pressing back the rib 23 which hasbeen bent out by the Welting machine and hold these parts untilretaining tacks can be driven. With the parts thus held the operativemay then cut the welt ends of! evenly and accurately against the stops15 by means of a cutting knife 17 shown in connection with Fig. 5. Whenthe upper is finished the slides 10 are allowed to be returned by thesprings and the slide 3 returned to its initial position in which theshoe. may be removed and another piece of work substituted.

Various modifications may obviously be made in the form and arrangementof the parts of the embodiment of my invention shown without departingfrom its spirit.
